Mueller has enough evidence to charge Trump's former national security advisor

Special counsel Robert Mueller has reportedly collected sufficient evidence to charge US president Donald Trump’s former national security advisor and his son in the investigation into alleged collusion between Trump aides and Russia.

Citing multiple sources familiar with the investigation, NBC said that Mueller’s team was looking at possible charges of money laundering and lying to federal agents, and Michael Flynn’s role in a possible plan to remove an opponent of the Turkish president from the US in exchange for millions of dollars.

Barry Coburn, a lawyer for Michael Flynn Jr, declined to comment and Robert Kelner, Flynn’s lawyer did not immediately respond to a request for comment.

Flynn Jr appeared to address the report in a tweet.

The SJW are out in full this morning....the disappointment on your faces when I don’t go to jail will be worth all your harassment...

In a week which began with Mueller’s indictment on financial charges of former Trump campaign manager Paul Manafort and campaign aide Rick Gates – and news of a guilty plea and potential cooperation by a former foreign policy adviser - White House and Republican party sources have sought to increase pressure on Mueller.

Mueller is increasing pressure on Flynn following his indictment of Manafort, the NBC report said.

The Republican speaker of the House of Representatives, Paul Ryan, said on Sunday Mueller should not be fired or step down.

“We need to let these career professionals do their jobs, see it through … I don’t think he should be stepping down and I don’t think he should be fired,” Ryan told Fox News Sunday.

Flynn served 24 days as Trump’s national security adviser but resigned after it was discovered he had misrepresented his contacts with a Russian diplomat to Vice-President Mike Pence.

The NBC report said lawyers for Flynn and his son, Michael G Flynn, who worked with his father, declined to comment.
